But ! the prob is the GCC by Apple !! who work in couple with LLVM , that mean is not an “PURE” GCC, more, he is an outdate version of LLVM_GCC , is the 4.2 version, we are today at 4.8 ( many improuvement inside)

& many app don’t be compiled as well for this reason…

The best way is to get for sure “Command-Line-Tool” + an new version of GCC, even the 4.6

I leave the place to OSXDAILY.COM to make an tut’s about “how to install GCC on your Mac’s”
